The Novel Super-FEC Coding Scheme Based on the Block Turbo Code for Long-Haul Optical Transmission Systems
A novel Super Forward Error Correction (Super-FEC) coding scheme (viz: the BTC code pattern of BCH(64,57) × BCH(64,57)) based on the Block Turbo Code (BTC) in long-haul optical transmission systems is proposed in this paper. The BTC of Bose-Chaudhur-Hocguenghem (BCH)(64,57)×BCH(64,57) has been constructed, simulated and analyzed. The simulation results and the performance analyses show that the Net Coding Gain (NCG) of BCH(64,57)×BCH(64,57) code at the sixth iteration is 0.35dB more than that of Reed-Solomon (RS)(255,239) + Convolutional Self Orthogonal Code (CSOC) (k0/n0 =6/7, J=8) code in ITU-T G.975.1 at the third iteration for a BER of 10-12 and the novel BTC has the advantageous characteristics such as the shorter component code and the rapid encoding/decoding speed, these advantages reduce not only the complexity for implementing the software/hardware but also the time delay for the encoding/decoding. Therefore, the novel BTC coding scheme can be used in large capacity, high-speed and ultra long-haul optical transmission systems. At last, the design and implementation of the novel BTC are also discussed.
